Abstract

The application discloses a platform zero position application system and method based on a horizontal rotary injection molding machine, and relates to the field of horizontal rotary injection molding machines. The system records the forward rotation platform zero position and the reverse rotation platform zero position respectively, and during the operation of the injection molding machine, the corresponding platform zero position, i.e. the forward rotation platform zero position or the reverse rotation platform zero position, is selected for the mold closing to the bottom judgment according to the turning state of the intermediate platform, i.e. the forward rotation to position state or the reverse rotation to position state. The system solves the problem that due to the machining and installation errors of two sets of molds, the position of the intermediate platform corresponding to the mold closing to the bottom in the forward rotation state is different from the position of the intermediate platform corresponding to the mold closing to the bottom in the reverse rotation state, and further causes the problem that when one zero position is used to judge whether the mold is closed to the bottom, the machine can normally close to the bottom when the intermediate platform is turned to one side, but cannot close to the bottom or the position after closing to the bottom is less than zero when the intermediate platform is turned to the other side.

Description

Technical Field

[0001] This invention relates to the field of horizontal rotary injection molding machines, and more particularly to a platform zero-position application system and method based on a horizontal rotary injection molding machine. Background Technology

[0002] The horizontal rotary injection molding machine has an intermediate platform and is equipped with two sets of molds. In existing technology, during automatic mold adjustment and zeroing or manual platform zeroing, the host computer only saves one platform zero position and records this position as the zero position. During subsequent production, regardless of whether the intermediate platform is rotating clockwise or counterclockwise, this single position is used to determine whether the mold is fully closed. However, due to machining and installation errors in the two sets of molds, the position of the intermediate platform when it is fully closed will differ depending on whether it is rotating clockwise or counterclockwise. Therefore, the current problem is:

[0003] Due to processing and installation errors in the two sets of molds, the position of the intermediate platform when closing the mold differs between clockwise and counterclockwise rotation. This can lead to situations where the intermediate platform can close properly to the bottom when rotated to one side, but not to the bottom or the position after closing is less than 0 when rotated to the other side. This causes machine alarms and production halts, significantly extending the injection molding machine's production cycle and reducing the customer's economic benefits. Summary of the Invention

[0004] To address the issue that during automatic mold adjustment and manual platform zeroing, the host computer only stores one platform zero position. During production, regardless of whether the intermediate platform rotates clockwise or counterclockwise, this single position is used to determine if the mold is fully closed. This leads to situations where the intermediate platform closes completely when rotated to one side, but not completely when rotated to the other side, or the position after closing is less than 0. This invention proposes a platform zero-position application system based on a horizontal rotary injection molding machine. The horizontal rotary injection molding machine includes a first template, an intermediate platform, and a second template arranged sequentially. A first set of molds is located between the first template and the intermediate platform, and a second set of molds is located between the intermediate platform and the second template. The first set of molds includes a first moving mold and a first fixed mold. The first fixed mold is mounted on the first template, and the first moving mold is mounted on the intermediate platform. The second set of molds includes a second moving mold and a second fixed mold. The second fixed mold is mounted on the second template, and the second moving mold is mounted on the intermediate platform, located away from the first moving mold. The platform zero-position application system includes:

[0005] The zero-position setting module for the forward rotation platform includes:

[0006] The automatic zeroing unit for forward rotation is used to start automatic mold adjustment after the intermediate platform is rotated into place. During the mold adjustment process, it controls the intermediate platform to move towards the first template while simultaneously controlling the second template to move towards the intermediate platform until the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. The current position of the intermediate platform is recorded as the zero position of the forward rotation platform.

[0007] The reversing platform zero-position setting module includes:

[0008] The automatic zeroing unit for reversing is used to start automatic mold adjustment after the intermediate platform is reversed into position. During the mold adjustment process, it controls the intermediate platform to move towards the first template while simultaneously controlling the second template to move towards the intermediate platform until the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. The current position of the intermediate platform is recorded as the zero position of the forward rotating platform.

[0009] The first application module is used in the production process of a horizontal rotary injection molding machine to obtain the current position of the intermediate platform when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted. It also obtains the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform and determines whether the straight-line distance is within the preset range. If it is, it means that the mold is closed to the bottom.

[0010] The second application module is used in the production process of a horizontal rotary injection molding machine to obtain the current position of the intermediate platform when the intermediate platform reverses to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. It also obtains the straight-line distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform and determines whether the straight-line distance is within the preset range. If it is, it means that the mold is closed to the bottom.

[0011] Furthermore, the system also includes:

[0012] The mold opening module is used to control the middle platform to move away from the first template and the second template to move away from the middle platform after the mold is closed to the bottom, until the middle platform reaches the first set position between the first template and the second template and the second template reaches the second set position. At this time, the middle platform is in the mold opening state.

[0013] Furthermore, the judgment rule for the complete fit between the first moving mold and the first fixed mold is as follows:

[0014] If the linear distance the intermediate platform or the first template moves within a preset time period is less than the corresponding preset value, it indicates that the first moving mold and the first fixed mold are completely fitted together.

[0015] Furthermore, the rule for determining whether the second moving mold and the second fixed mold are completely fitted is as follows:

[0016] If the linear distance the intermediate platform or the second template moves within a preset time period is less than the corresponding preset value, it indicates that the second moving mold and the second fixed mold are completely fitted together.

[0017] Furthermore, the zero-position setting module of the forward rotation platform also includes:

[0018] The manual zeroing unit for forward rotation is used to observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold have completely fitted together when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform during the mold closing process after the intermediate platform has been rotated into place. If so, the current position of the intermediate platform is recorded as the zero position of the forward rotation platform.

[0019] Furthermore, the reversal platform zero-position setting module also includes:

[0020] The manual zeroing unit for reversing is used to observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold have completely fitted together when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform during the mold closing process after the intermediate platform has reversed into place. If so, the current position of the intermediate platform is recorded as the zero position of the reversing platform.

[0021] This invention also proposes a platform zero-position application method based on a horizontal rotary injection molding machine. The horizontal rotary injection molding machine includes a first template, an intermediate platform, and a second template arranged sequentially. A first set of molds is provided between the first template and the intermediate platform, and a second set of molds is provided between the intermediate platform and the second template. The first set of molds includes a first moving mold and a first fixed mold. The first fixed mold is mounted on the first template, and the first moving mold is mounted on the intermediate platform. The second set of molds includes a second moving mold and a second fixed mold. The second fixed mold is mounted on the second template, and the second moving mold is mounted on the intermediate platform, located on the side away from the first moving mold. The platform zero-position application method includes the following steps:

[0022] S1: After the intermediate platform rotates into place, start automatic mold adjustment. During the mold adjustment process, control the intermediate platform to move towards the first template while controlling the second template to move towards the intermediate platform. During the movement, determine in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted and the second moving mold and the second fixed mold are completely fitted. Record the current position of the intermediate platform as the zero position of the rotating platform.

[0023] After the intermediate platform is reversed into position, automatic mold adjustment is started. During the mold adjustment process, the intermediate platform is controlled to move towards the first template while the second template moves towards the intermediate platform. During the movement, it is determined in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted and the second moving mold and the second fixed mold are completely fitted. The current position of the intermediate platform is recorded as the zero position of the reversing platform.

[0024] S2: During the production process of the horizontal rotary injection molding machine, when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together, the current position of the intermediate platform is obtained, and the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform is obtained. It is determined whether the straight-line distance is within the preset range. If so, it means that the mold is closed to the bottom.

[0025] S3: After the intermediate platform rotates into place and the mold is closed to the bottom, control the intermediate platform to move away from the first template while controlling the second template to move away from the intermediate platform, until the intermediate platform reaches the first set position between the first template and the second template and the second template reaches the second set position, so that the intermediate platform is in the mold open state.

[0026] S4: When the intermediate platform is in the state of being fully open, control the intermediate platform to reverse into position. After the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted, obtain the current position of the intermediate platform and the straight distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform. Determine whether the straight distance is within the preset range. If so, it means that the mold closing is complete.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] (1) This invention initiates automatic mold adjustment after the intermediate platform rotates to its position. During the mold adjustment process, when the first moving mold and the first fixed mold are fully engaged, and the second moving mold and the second fixed mold are fully engaged, the current position of the intermediate platform is recorded as the zero position of the rotating platform. After the intermediate platform rotates to its position, automatic mold adjustment is initiated. During the mold adjustment process, when the first moving mold and the first fixed mold are fully engaged, and the second moving mold and the second fixed mold are fully engaged, the current position of the intermediate platform is recorded as the zero position of the reversing platform. After recording the zero positions of the rotating and reversing platforms, during the production process of the horizontal rotary injection molding machine, when the intermediate platform rotates to its position and the mold is closed, the current position of the intermediate platform is obtained, and the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform is obtained. It is determined whether the straight-line distance is within a preset range. If it is, it indicates that the mold is fully closed. When the intermediate platform rotates to its position and the mold is closed, the current position of the intermediate platform is obtained. The system determines the position of the intermediate platform and the straight-line distance from the current intermediate platform position to the zero position of the clockwise rotating platform. It then determines whether the straight-line distance is within a preset range. If so, it indicates that the mold is fully closed. The system records the zero positions of the clockwise and counterclockwise rotating platforms respectively. During the operation of the injection molding machine, it selects the corresponding platform zero position (clockwise or counterclockwise) based on the rotation state of the intermediate platform (clockwise or counterclockwise) to determine whether the mold is fully closed. This solves the problem that due to processing and installation errors in the two sets of molds, the position of the intermediate platform at the bottom of the mold when it is closed in clockwise and counterclockwise states differs. This can lead to the machine being able to close the mold fully when the intermediate platform rotates to one side, but not when it rotates to the other side, or the position after closing the mold is less than 0.

[0029] (2) This invention records the zero position of the clockwise platform and the zero position of the counterclockwise platform respectively, and selects the corresponding platform zero position (clockwise platform zero position or counterclockwise platform zero position) to determine the mold closing position during the operation of the injection molding machine based on the turning state of the intermediate platform (the turning state is clockwise or counterclockwise). This avoids the problem of frequent machine alarms, reduces the production cycle of the injection molding machine, and improves the economic benefits for customers. Attached Figure Description

[0031] Figure 2 This is a flowchart of a platform zero-position application method based on a horizontal rotary injection molding machine. Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] Example 1

[0034] In existing technology, regardless of whether the intermediate platform is rotating clockwise or counterclockwise, a single zero-position is used to determine whether the mold is fully closed. However, due to machining and installation errors in the two sets of molds, the position corresponding to the mold being fully closed during clockwise rotation differs from the position corresponding to the mold being fully closed during counterclockwise rotation. This leads to the problem that when using a single zero-position to determine whether the mold is fully closed, the machine may exhibit issues such as the intermediate platform closing correctly to one side but failing to close completely or having a position less than 0 after closing completely when rotating to the other side. Figure 1 As shown, this invention proposes a platform zero-position application system based on a horizontal rotary injection molding machine. The horizontal rotary injection molding machine includes a first template, an intermediate platform, and a second template arranged sequentially. A first set of molds is provided between the first template and the intermediate platform, and a second set of molds is provided between the intermediate platform and the second template. The first set of molds includes a first moving mold and a first fixed mold. The first fixed mold is mounted on the first template, and the first moving mold is mounted on the intermediate platform. The second set of molds includes a second moving mold and a second fixed mold. The second fixed mold is mounted on the second template, and the second moving mold is mounted on the intermediate platform, located on the side away from the first moving mold. The platform zero-position application system includes:

[0035] The zero-position setting module for the forward rotation platform includes:

[0036] The automatic zeroing unit for forward rotation is used to start automatic mold adjustment after the intermediate platform is rotated into place. During the mold adjustment process, it controls the intermediate platform to move towards the first template while simultaneously controlling the second template to move towards the intermediate platform until the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. The current position of the intermediate platform is recorded as the zero position of the forward rotation platform.

[0037] The zero-position setting module of the rotating platform also includes:

[0038] The manual zeroing unit for forward rotation is used to observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold have completely fitted together when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform during the mold closing process after the intermediate platform has been rotated into place. If so, the current position of the intermediate platform is recorded as the zero position of the forward rotation platform.

[0039] The reversing platform zero-position setting module includes:

[0040] The automatic zeroing unit for reversing is used to start automatic mold adjustment after the intermediate platform is reversed into position. During the mold adjustment process, it controls the intermediate platform to move towards the first template while simultaneously controlling the second template to move towards the intermediate platform until the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. The current position of the intermediate platform is recorded as the zero position of the forward rotating platform.

[0041] The reversal platform zero-position setting module also includes:

[0042] The manual zeroing unit for reversing is used to observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold have completely fitted together when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform during the mold closing process after the intermediate platform has reversed into place. If so, the current position of the intermediate platform is recorded as the zero position of the reversing platform.

[0043] The rule for determining whether the first moving mold and the first fixed mold are completely fitted is as follows:

[0044] If the linear distance the intermediate platform or the first template moves within a preset time period is less than the corresponding preset value, it indicates that the first moving mold and the first fixed mold are completely fitted together.

[0045] The rule for determining whether the second moving mold and the second fixed mold are completely fitted is as follows:

[0046] If the linear distance the intermediate platform or the second template moves within a preset time period is less than the corresponding preset value, it indicates that the second moving mold and the second fixed mold are completely fitted together.

[0047] The first application module is used in the production process of a horizontal rotary injection molding machine to obtain the current position of the intermediate platform when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted. It also obtains the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform and determines whether the straight-line distance is within the preset range. If it is, it means that the mold is closed to the bottom.

[0048] The system also includes:

[0049] The mold opening module is used to control the middle platform to move away from the first template and the second template to move away from the middle platform after the mold is closed to the bottom, until the middle platform reaches the first set position between the first template and the second template and the second template reaches the second set position. At this time, the middle platform is in the mold opening state.

[0050] The second application module is used to control the intermediate platform to reverse into position when the intermediate platform is in the open-to-the-end state during the production process of the horizontal rotary injection molding machine. After the mold is closed, that is, when the first moving mold and the first fixed mold are fully engaged and the second moving mold and the second fixed mold are fully engaged, the module obtains the current position of the intermediate platform and the straight-line distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform. It then determines whether the straight-line distance is within the preset range. If it is, it indicates that the mold is closed to the end.

[0051] This invention involves automatically adjusting the mold after the intermediate platform rotates to its forward position. During this adjustment process, when the first moving mold and the first fixed mold are fully engaged, and the second moving mold and the second fixed mold are fully engaged, the current position of the intermediate platform is recorded as the zero position of the forward rotation platform. After the intermediate platform rotates to its reverse position, automatic mold adjustment is initiated again. During this adjustment process, when the first moving mold and the first fixed mold are fully engaged, and the second moving mold and the second fixed mold are fully engaged, the current position of the intermediate platform is recorded as the zero position of the reverse rotation platform. After recording the zero positions of the forward and reverse rotation platforms, during the production process of the horizontal rotary injection molding machine, when the intermediate platform rotates to its forward position and the mold is closed, the current position of the intermediate platform is obtained, and the straight-line distance from the current position of the intermediate platform to the zero position of the forward rotation platform is obtained. It is then determined whether the straight-line distance is within a preset range; if so, it indicates that the mold is fully closed. When the intermediate platform rotates to its reverse position and the mold is closed, the current position of the intermediate platform is obtained. The system determines the position of the platform and obtains the straight-line distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform. It then determines whether the straight-line distance is within a preset range. If so, it indicates that the mold is fully closed. The system records the zero positions of the clockwise and counterclockwise rotating platforms separately. During the operation of the injection molding machine, it selects the corresponding platform zero position (clockwise or counterclockwise) based on the rotation state of the intermediate platform (clockwise or counterclockwise) to determine whether the mold is fully closed. This solves the problem that due to processing and installation errors in the two sets of molds, the position of the intermediate platform at the bottom of the mold when it is closed in clockwise and counterclockwise states differs. This can lead to the machine being able to close the mold fully when the intermediate platform rotates to one side, but not when it rotates to the other side, or the position after closing the mold is less than 0.

[0052] Example 2

[0053] like Figure 2As shown, this invention also proposes a platform zero-position application method based on a horizontal rotary injection molding machine. The horizontal rotary injection molding machine includes a first template, an intermediate platform, and a second template arranged sequentially. A first set of molds is provided between the first template and the intermediate platform, and a second set of molds is provided between the intermediate platform and the second template. The first set of molds includes a first moving mold and a first fixed mold. The first fixed mold is installed on the first template, and the first moving mold is installed on the intermediate platform. The second set of molds includes a second moving mold and a second fixed mold. The second fixed mold is installed on the second template, and the second moving mold is installed on the intermediate platform, located on the side away from the first moving mold. The platform zero-position application method includes the following steps:

[0054] S1: After the intermediate platform rotates into place, start automatic mold adjustment. During the mold adjustment process, control the intermediate platform to move towards the first template while controlling the second template to move towards the intermediate platform. During the movement, determine in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted together and the second moving mold and the second fixed mold are completely fitted together (that is, the mold has been closed to the bottom). Record the current position of the intermediate platform as the zero position of the rotating platform.

[0055] It should be noted that after recording the zero position of the rotating platform (i.e., the intermediate platform rotates into place and is closed to the bottom), it also includes: controlling the intermediate platform to move away from the first template while controlling the second template to move away from the intermediate platform, until the intermediate platform reaches the first set position between the first template and the second template and the second template reaches the second set position, so that the intermediate platform is in the state of being fully open.

[0056] After the intermediate platform is in the mold opening state, control the intermediate platform to reverse into position, start automatic mold adjustment, and control the intermediate platform to move towards the first template while controlling the second template to move towards the intermediate platform during the mold adjustment process. During the movement, it is judged in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted, and the second moving mold and the second fixed mold are completely fitted. The current position of the intermediate platform is recorded as the zero position of the reversing platform.

[0057] It should be noted that the zero positions of the clockwise and counterclockwise platforms in step S1 can also be obtained by the following methods:

[0058] After the intermediate platform rotates into place, during the mold closing process, observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold are completely fitted when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform. If so, record the current position of the intermediate platform as the zero position of the rotating platform (manual zeroing during rotation). After recording the zero position of the rotating platform, control the intermediate platform to move away from the first template while controlling the second template to move away from the intermediate platform, until the intermediate platform reaches the first set position between the first template and the second template, and the second template reaches the second set position, so that the intermediate platform is in the mold opening state.

[0059] With the intermediate platform in the fully open state, after the intermediate platform is reversed into position, during the mold closing process, observe whether the first moving mold and the first fixed mold, and the second moving mold and the second fixed mold are completely fitted when the intermediate platform moves towards the first template and the second template moves towards the intermediate platform. If so, record the current position of the intermediate platform as the zero position of the reverse platform (reverse manual zeroing).

[0060] S2: During the production process of the horizontal rotary injection molding machine, when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together, the current position of the intermediate platform is obtained, and the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform is obtained. It is determined whether the straight-line distance is within the preset range. If so, it means that the mold is closed to the bottom.

[0061] S3: After the intermediate platform rotates into place and the mold is closed to the bottom, control the intermediate platform to move away from the first template while controlling the second template to move away from the intermediate platform, until the intermediate platform reaches the first set position between the first template and the second template and the second template reaches the second set position, so that the intermediate platform is in the mold open state.

[0062] S4: When the intermediate platform is in the state of being fully open, control the intermediate platform to reverse into position. After the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted, obtain the current position of the intermediate platform and the straight distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform. Determine whether the straight distance is within the preset range. If so, it means that the mold closing is complete.

[0063] This invention records the zero positions of the clockwise and counterclockwise platforms separately, and during the operation of the injection molding machine, selects the corresponding platform zero position (clockwise platform zero position or counterclockwise platform zero position) based on the turning state of the intermediate platform (clockwise or counterclockwise positioning) to determine whether the mold is fully closed. This avoids the problem of frequent machine alarms, reduces the production cycle of the injection molding machine, and improves the economic benefits for customers.

The first application module is used in the production process of a horizontal rotary injection molding machine to obtain the current position of the intermediate platform when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted. It also obtains the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform and determines whether the straight-line distance is within the preset range. If it is, it means that the mold is closed to the bottom. The second application module is used in the production process of a horizontal rotary injection molding machine to obtain the current position of the intermediate platform when the intermediate platform reverses to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together. It also obtains the straight-line distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform and determines whether the straight-line distance is within the preset range. If it is, it means that the mold is closed to the bottom.

If so, the current position of the intermediate platform is recorded as the zero position of the reversing platform.

7. A platform zero-position application method based on a horizontal rotary injection molding machine, characterized in that, The horizontal rotary injection molding machine includes a first template, an intermediate platform, and a second template arranged sequentially. A first set of molds is provided between the first template and the intermediate platform, and a second set of molds is provided between the intermediate platform and the second template. The first set of molds includes a first moving mold and a first fixed mold. The first fixed mold is installed on the first template, and the first moving mold is installed on the intermediate platform. The second set of molds includes a second moving mold and a second fixed mold. The second fixed mold is installed on the second template, and the second moving mold is installed on the intermediate platform, located on the side away from the first moving mold. The platform zero-position application method includes the following steps: S1: After the intermediate platform rotates into place, start automatic mold adjustment. During the mold adjustment process, control the intermediate platform to move towards the first template while controlling the second template to move towards the intermediate platform. During the movement, determine in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted and the second moving mold and the second fixed mold are completely fitted. Record the current position of the intermediate platform as the zero position of the rotating platform. After the intermediate platform is reversed into position, automatic mold adjustment is started. During the mold adjustment process, the intermediate platform is controlled to move towards the first template while the second template moves towards the intermediate platform. During the movement, it is determined in real time whether the straight distance moved by the intermediate platform within the preset time is less than the corresponding preset value. If so, it means that the first moving mold and the first fixed mold are completely fitted and the second moving mold and the second fixed mold are completely fitted. The current position of the intermediate platform is recorded as the zero position of the reversing platform. S2: During the production process of the horizontal rotary injection molding machine, when the intermediate platform rotates to the correct position and after the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted together and the second moving mold and the second fixed mold are fully fitted together, the current position of the intermediate platform is obtained, and the straight-line distance from the current position of the intermediate platform to the zero position of the rotating platform is obtained. It is determined whether the straight-line distance is within the preset range. If so, it means that the mold is closed to the bottom. S3: After the intermediate platform rotates into position and the mold is closed to the bottom, control the intermediate platform to move away from the first template while controlling the second template to move away from the intermediate platform, until the intermediate platform reaches the first set position between the first template and the second template and the second template reaches the second set position, so that the intermediate platform is in the mold open state. S4: When the intermediate platform is in the state of being fully open, control the intermediate platform to reverse into position. After the mold is closed, that is, when the first moving mold and the first fixed mold are fully fitted and the second moving mold and the second fixed mold are fully fitted, obtain the current position of the intermediate platform and the straight distance from the current position of the intermediate platform to the zero position of the clockwise rotating platform. Determine whether the straight distance is within the preset range. If so, it means that the mold closing is complete.
